(U3) Cellular Energetics

What is cellular respiration?

• process in which cells break down glucose in the presence of oxygen which results in the release of energy in the form of ATP

• process in which cells synthesize glucose from carbon dioxide and water

• process in which cells store energy in the form of glucose

• process in which cells convert sunlight into chemical energy

Where does cellular respiration take place?

• mitochondria

• chloroplast

• nucleus

• ribosome

What is the cellular respiration equation?

• C6H12O6+6O2---> 6CO2+6H2O+ATP

• C6H12O6+6O2---> 6CO2+6H2O

• C6H12O6+6CO2---> 6O2+6H2O+ATP

• C6H12O6+O2---> CO2+H2O+ATP

What is photosynthesis?

• process in which energy in light, carbon dioxide, and water make glucose and oxygen

• process in which glucose and oxygen are converted into energy and water

• method by which plants absorb nutrients from the soil

• technique used by animals to produce energy from food

What is the photosynthesis equation?

• 6CO2 + 6H2O --> light energy --> C6H12O6 + 6O2

• C6H12O6 + 6O2 --> 6CO2 + 6H2O

• 6O2 + C6H12O6 --> light energy --> 6CO2 + 6H2O

• 6H2O + 6O2 --> light energy --> C6H12O6 + 6CO2

Where does photosynthesis occur?

• chloroplasts (plant cells)

• mitochondria

• nucleus

• ribosomes

Cellular respiration occurs in what organisms?

• all organisms (plants and animals)

• only animals

• only plants

• only microorganisms

Photosynthesis occurs in what organisms?

• plants (also algae and some bacteria)

• animals

• fungi

• viruses

What are the reactants of photosynthesis?

• carbon dioxide and water (CO2 and H2O)

• oxygen and glucose (O2 and C6H12O6)

• nitrogen and hydrogen (N2 and H2)

• methane and oxygen (CH4 and O2)

What are the products of photosynthesis?

• glucose and oxygen (C6H12O6 + 6O2)

• carbon dioxide and water (CO2 + H2O)

• glucose and carbon dioxide (C6H12O6 + CO2)

• oxygen and water (O2 + H2O)
